Django之Admin
二.定制Admin
在admin.py中只需要讲Mode中的某个类注册，即可在Admin中实现增删改查的功能，如：
admin.site.register(models.UserInfo) #admin.site.register(models.UserInfo,admin.ModelAdmin) # 默认 admin.ModelAdmin
这种方式比较简单，如果想要进行更多的定制操作，需要利用ModelAdmin进行操作，如：
方式一：
class UserAdimin(admin.ModelAdmin): def no_column(self,obj): return 'xxxxxx' list_display = ['name','email',no_column,'nickname'] admin.site.register(models.UserInfo,UserAdimin) 方式二： @admin.register(models.UserInfo) class UserAdimin(admin.ModelAdmin): def no_column(self,obj): return 'xxxxxx' list_display = ('name','email',no_column,'nickname') #list_display = (,)或[ ]
1. list_display，列表时，定制显示的列。
2.list_display_links，列表时，定制列可以点击跳转。
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email',no_column)
list_display_links = ('email',) #逗号
def no_column(self,obj):
return 'xxxxxx'
admin.site.register(models.UserInfo,UserAdimin)
3. list_filter，列表时，定制右侧快速筛选。
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email',)
list_filter = ('name','group')
还可以：
from django.utils.translation import ugettext_lazy as _
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email',)
class Ugg(admin.SimpleListFilter):
title = _('萨达额')
parameter_name = 'xxxx'
def lookups(self, request, model_admin):
"""
显示筛选选项
:param request:
:param model_admin:
:return:
"""
return models.UserGroup.objects.values_list('id', 'title')
# return models.UserGroup.filter(id__gt=10).objects.values_list('id', 'title')
def queryset(self, request, queryset):
"""
点击查询时，进行筛选
:param request:
:param queryset:
:return:
"""
v = self.value()
return queryset.filter(group_id=v)
list_filter = ('name',Ugg)
4. list_select_related，列表时，连表查询是否自动select_related
from django.utils.translation import ugettext_lazy as _
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email','group')
class Ugg(admin.SimpleListFilter):
title = _('萨达额')
parameter_name = 'xxxx'
def lookups(self, request, model_admin):
"""
显示筛选选项
:param request:
:param model_admin:
:return:
"""
return models.UserGroup.objects.values_list('id', 'title')
# return models.UserGroup.filter(id__gt=10).objects.values_list('id', 'title')
def queryset(self, request, queryset):
"""
点击查询时，进行筛选
:param request:
:param queryset:
:return:
"""
v = self.value()
if v:
return queryset.filter(group_id=v)
else:
return request
list_filter = ('group',Ugg)
list_select_related = ('group',)
5. 分页相关
# 分页，每页显示条数
list_per_page = 100
# 分页，显示全部（真实数据<该值时，才会有显示全部）
list_max_show_all = 200
# 分页插件
paginator = Paginator
6. list_editable，列表时，可以编辑的列
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email')
list_editable = ('email',)
7. search_fields，列表时，模糊搜索的功能
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email')
search_fields = ('name','email')
8. date_hierarchy，列表时，对Date和DateTime类型进行搜索
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email','ctime')
date_hierarchy = 'ctime'
9. preserve_filters，详细页面，删除、修改，更新后跳转回列表后，是否保留原搜索条件
10. save_as = False，详细页面，按钮为“Sava as new” 或 “Sava and add another”
11. save_as_continue = True，点击保存并继续编辑
save_as_continue = True # 如果 save_as=True，save_as_continue = True， 点击Sava as new 按钮后继续编辑。 # 如果 save_as=True，save_as_continue = False，点击Sava as new 按钮后返回列表。 New in Django 1.10.
12. save_on_top = False，详细页面，在页面上方是否也显示保存删除等按钮
13. inlines，详细页面，如果有其他表和当前表做FK，那么详细页面可以进行动态增加和删除
class UserInfoInline(admin.StackedInline): # TabularInline 效果不一样
extra = 0
model = models.UserInfo
class UserGroupAdmin(admin.ModelAdmin):
list_display = ('title',)
inlines = [UserInfoInline, ]
admin.site.register(models.UserGroup,UserGroupAdmin)
14. action，列表时，定制action中的操作
class UserAdimin(admin.ModelAdmin):
list_display = ('name','email','ctime')
def func(self, request, queryset):
# print(self, request, queryset)
print(request.POST.getlist('_selected_action'))
print('代码来了。。。。')
func.short_description = "中文显示自定义Actions"
actions = [func, ]
15. 定制HTML模板
add_form_template = None change_form_template = None change_list_template = None delete_confirmation_template = None delete_selected_confirmation_template = None object_history_template = None
# change_list_template = ['list.html']
